2 SMBJ5.0A-TR, A-TR SMBJ188A-TR, A-TR TRANSIL Features Peak pulse power: 600 W (10/1000 µs) Stand off voltage range: from 5 V to 188 V Uni and bidirectional types Low clamping factor Fast response time JEDE registered package outline Description The SMBJ series are TRANSIL diodes designed specifically for protecting sensitive equipment against transient overvoltages. Transil diodes provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied I s.
